Took the boat out for the first time in 3 months because my job took me overseas. I stabalized the gas and tried to lay the engines up properly before I left. Took my boy out for a ride Sunday afternoon and the boat ran great for 30-45 minutes, but when we picked up to go to one last fishing hole the port engine acted as though it was running out of gas. I had over a half a tank. Well limped back in on one engine but was able to get the port engine running at the launch. When I tried to throttle her up by depressing the button on the side of the throttle she will get up to about 3000 rpm and start surging between 2800 and 3500 rpm and go no higher. I tried this in the driveway with cooling water supplied with the garden hose and the same thing was going on with both engines. Is this normal?

I changed out the fuel hose on the port side because that had not been done since I purchased the boat. Also replaced both fuel/water filter elements and checked for tightness in all fittings. Tried to run the port engine on an auxillary tank and it did the same thing. They only have 100 hours on them. I will take it to the dealer if I can't find an easy fix any suggestions? Thanks

Did you check to see if all spark plugs are fireing by taking one at a time off?
